I-IOG GREASER.

Application filed July 19, 1926. Serial No. 123,558.

T his invention relates to lio-g greasers, and particularly to a devicewhich may be termed a rubbing post, having novel means by which greaseis automatically applied to the a rubbing surface in order that thegrease will be smeared on that portion of the hog which contacts therubbing surface; this invention being distinguished from hog oilers forthe reason that the application of grease is ad vantageous over theapplication of oil, since grease will prove of greater benefit to theskin of the animal and at the same time it will close the pores of theparasite and hasten the destruction of the parasite.

lt is furthermore an object of this invention to produce a rubbing postassociated with a grease applicator, so arranged as to be automaticallymovable with relation to the. rubbing post and effective to distributegrease on the rubbing surface of the post. The grease distributor may beso mounted as to be moved by pressure of the animal during the rubbingprocess, and under certain conditions, it is movable by force of thewind so that proper distribution of the grease will be effected as theanimal is using the rubbing post, or, as stated, it may be distributedby the action of relatively strong wind currents.

lt is a still further object of this invention to provide a greaseholder having novel means by which it is rotatably mounted on the post;and it is furthermore an object of the invention to produce a device ofthe character indicated which will be comparatively inexpensive toproduce and maintain.

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed.

ln describing the invention in detail, referenee will be had to theaccompanying drawings forming part of this application, wherein likecharacters denote corresponding parts in the several views, and inwhich- Figure 1 illustrates a View in elevation of a post and applicatorembodying the invention- Figure 2 illustrates a view in elevation of thedevice in a position at right angles to thatl shown in Fig. 1;

Figure 3 illustrates a sectional view on the line 3-3 of Fig. 2; and

Figure 4 illustrates a top plan View of the device.

In these drawingU denotes a suitable post having a rope or other element(5 wrapped around it, which constitutes the rubbing surface. Thisrubbing surface may be located a suitable distance above the ground inwhich the post is anchored, and as this is a matter of proportion, itneed not be specified particularly. YVhile rope is found to have thequalities requisite for producing the rubbing surface, it also issuiiiciently absorbent to retain the grease in quantities which wouldprove effective for the use intended, and hence it is thought to be thepreferred material for the rubbing surface, although the inventors donot wish to be limited with respect to this.

The grease applicator or holder comprises, in the present embodiment ofthe invention, a bottom 7, a top 8, side walls 9 and 10, and a closureor door 11. The door is preferably provided with a hinge 12 that isanchored to the bottom 7 and the door may be held closed by a hasp 13and staple 14, which latter is anchored to the top of the casing.

As a means for rotatably applying the closure or casing to the post, thetop 8 eX- tends over the top of the post, and it is rotatably mounted ona stud or pin 15 anchored to the post and projecting from the topthereof through an aperture 16. A curved plate or strap 17 embraces thepost below the rubbing surface and its ends are connected to the sides 9and 10 of the case. Preferably one end is secured to a side 9 byfastenings such as screws, whereas the other end may be applied to afastening- 18 such as :a staple, in order that when desired, the strapmay be removed from the staple and the container may be dislodged fromthe Jost.

l A follower 19 is movable within the grease container and it is urgedinwardly by pressing means 20 such as springs of such strength as toovercome the resistance of grease 21 which be contained in the casebetween the follower and the rubbing surface. It is seen, of course,that the container does not have a. wall :at the inner edge, but thatthe grease is free to be discharged at the inner edge of the containerinto contact with the rubbing surface. Preferably the outer ends of thesprings are attached to a plate or board 22 and the inner ends of thesprings are attached to the iolloner in order that the follower undsprings` may be removed from the container as u unit whenthe eontaineris to be replenished with Lgrease.

From an inspection of Fig. 3, it will be apparent that the containerbeing rotatably mounted on the post will move around the post, due tothe pressure of the animal while in the met of rubbing, and therefore,grease 'will be spread on the rubbing surface and it will, of course, betaken up by the animal using the post. Se long as a supply of g'reuee ismaintained in the container, the upiieaiou oit' grease to the animal7will be praetir-allyr automatic and the post will therefore be u matterof relie't' to the animal using' it.

TWe claim:

l. ln n rubbing post, a post having' an abf=zorbent rubbing surface, agrease container rotatably mounted on the post, and means for holdingthe grease in the container in content with the rubbing surface.

2. In a rubbing post, n post having a rubbingsurface, a device rotatablymounted on the poet and operative to distribute grease ou the exteriorof the rubbing1 uurlnee.

3. In a hog greener, a rubbing post hnving' a rubbing surface, a greasecarrier rotatably mounted thereon, and menne associated with the gre-neeearrier 'lor forcing' grease into contact with the rubbing' surface.

Ll. l hog' greaser con'un'ising :L poet having ay Iibrous rubbinglsurface, a gre-nee applilator rotatably mounted with relation to thepoet for movement around the rubbing Surface, and means for 'forcinggrease from the :xliplieator into Contact with the rubbingr surface.

In a hog grreaeer, a rubbing post, a fontainer mounted for roi ationuround the rubbilig surface of the post, a follower within the containeroperative to pre.' gremio into engagement with the rubbing' nurture, andmeans: for retaining the parte in opel-allrerelation Within thecontainer.
